a "bostleg" is the mix between a bootleg and an original sound track.
The participants in a bostleg tournament have to mix/overlay a chosen original extract from a video (which can be a film, cartoon, documentary, video game or whatever) with a new original sound track. See the example below :

- The original video can be altered (the participant may add Sound FXs or edit the video as long as it still looks like a real film excerpt, not a video clip)

- The original video's sounds and dialogues can be kept in the final mix. (it's even advised to do so in order to make the bostleg more vivid)
the audio track must be chosen between the three original tracks of Danger's latest EP (09/17 2007) and can not be edited
